Extending my network

I have a WRT54G network at home with WEP security enabled. I want to extend my network to my relative's house who lives about 300 feet from my house. Can this be done? If so, how? Thanks! Also, I want it so that both places have the same SSID, as if there is one giant network. Not 2 separate ones. I also want to be able to share files between my computers and my relative's computers; thus being on the same workgroup.

well the distance will depend on whats between the 2 routers. you can use 2 WRT54G routers with Alchemy, Satori or Talisman in WDS mode. both use the same SSID, one giant network. your probably going to have to put routers on the very edge closest to the other houses.

You should be able to build this and put it onto one of the antenna on your current WRT54G. Point it at your relatives house. They should be able to log onto your system if they have something setup with your wep key.
